When assessing the price of a robot dog, you must look beyond the sticker price and evaluate the Degrees of Freedom (DoF), Payload Capacity, and Battery Life. Entry-level models (Consumer/Educational) typically range from $500 to $3,000, featuring 12 DoF and basic obstacle avoidance. Industrial-grade models (Inspection/Security) can cost between $15,000 and $70,000, offering IP67 waterproofing, LiDAR mapping, and the ability to carry sensors up to 10kg. Always verify if the price includes the SDK (Software Development Kit), as open-source access is vital for secondary development.
